What is an obscurial?

An Obscurial is a term used in the wizarding world of Harry Potter to describe a young wizard or witch who suppresses their magic due to traumatic experiences. The suppression of their magic creates a dark and powerful force known as an Obscurus that can be uncontrollable and dangerous.

Obscurials are rare, as most young witches and wizards are trained to control their magical abilities from an early age. However, those who are mistreated or forced to repress their powers can develop an Obscurus, which can cause destruction and harm to both themselves and others.

The character of Creedence Barebone in the movie "Fantastic Beasts and Where to Find Them" is an example of an Obscurial. He had repressed his magical abilities due to an abusive upbringing, leading to the creation of an Obscurus that threatened to destroy the city of New York.
